GRAIN-DRILL.

SPECIFICATION forming part of Letters Patent No. 234,7550, datedNovember Application filed July er, leso. (Model.)

To all whom it may concern:

Be it known that I, JACOB H. SHREINER, of Harrisburg, Pennsylvania, haveinvented a. new and useful Improvement in Grain-Drills, of which thefollowing is a specification.

My invention relates to improvelnents lnailll y in broadcast seed-drillsin which the seed is distributed as it falls on a dividing-shieldarranged in the lower part of the drill-boot, the drill point or hoebeing specially patterned and recessed to allow the seed to fall widely,deposited between the heels of the shear-footings thereof, they beingabrllptly terminated at their widest cross-section, where they aresupplemented by detachable return-bits or relay-shears, whereby thelifted mold is cleft and replaced upon the seed evenly and orderly overthe whole drilled area, the clods being cut and disposed of moreadvantageously in the operation, and the hoes being also kept cleaner inthe operation, than heretofore, a guard being also arranged in thehollow at the foot of said boot, whereby its openings for the exit ofthe seed are kept unclogged.

The principal objects or intents of my present invention are declared tobe substantially as follows: first, the dwarfed hoe, made witll short,simple, concaved lnold-sides and wide furrow-openingtreads prolongedrearward farther than the said mold-sides, in combination directly withdrill-boot, made with forwardlyextended foot, all in one piece, the saidparts being constructed and arranged in sucll manner that the mold mayfall v and close the furrow before said treads have passed sectionsthereof 5 second, an anti-clog guard arranged longitudinally in the footof the drill, to keep the seed-aperture unstopped by ground, stones, &c.5 third, a seed-distributer of peculiar construction, detachably mountedbeneath the drill-boot and secured thereto, and arranged to present itsbody centrally beneath the drillboot outlet, which is speciallycontracted by thickening the boot-wall to make said outlet funicular,and to cause the seed to fall collectedly onto the seed-distributer, tosow evenly on inclined as well as on level ground, fourth, supplementalblades attached to the rear ends of the dwarfed hoe by rivets enteredthrough mold pulverized upon the furrow without displacing the seeddeposited therein; fifth, the colnbination of drill-boot, dwarfed hoe,anticlog guard, and seed-distributer, all specially' adapted andarranged for broadcast sowing. I attain these objects by mechanismillustrated in the accompanying drawings, in which- Figure l representsa perspective view of my invention,the attaching parts being brokenaway. Fig. 2 represents a vertical sectional view of my drill-boot withthe seed-distributer andthe anti-clog guard inserted therein. Fig. 3represents a perspective view of my drillhoe with retllrn-bits detached.Fig. et represents a perspective view of my left nlold returnbit. Fig. 5represents a perspective View of my anti-clog guard with a modifiedseeddistributer mounted thereon. Fig. 6 represents a bottom view of mygrani-drill.

Similar letters denote similar parts throughout the several views.

The drill boot or tubeA is lnade ill the usual way at its top, with thearm A to attach it to the drag-bar D, and with staple g to attachthereto the stay-cllaill G. 0n said drill-boot, at about the mid heightof the front edge thereof, is formed the hook or shoulder F, withacute-angled notch thereunder, alld the shank ofsaid bootfrom thencedown is rabbeted and curved to form a seat for the stock of thedrill-hoe W XR, applied thereto, as shown in Fig. l, two rivets orbolts, N N', retaining it on the foot J of said drill-boot below, whileat its upper biased end, E, it is caught and retained ill place by saidhook F. Said hoe R YV X is lnade inform as shown in Figs. 3 and 6, itbeing dwarfed or abruptly terminated at its rear end. Its point WV is atriangular wedge, and its sides are simple or unreturned concaves X,they being shorter rearward than the shearing-treads R It', that themold may be caused to fall from them suddenly to cover the seed beforesaid treads have passed the same cross-section of furrow.

The treads or divergent shear-edges R R are hollowed out beneath to formthe offset L L next to the tread thereof, which offset affords, irst, asquare shoulder, against which arejamnled the flat llilts Q Q' ofthemold returnbits, joined firmly to the hoes by rivets n or bolts M M', asshown in Figs. 1 and; secv IOO ond, a shelter or spacein which the sownSeed may fall b roadcast and be covered unshoved. Said mold returnbitsare made as right and left devices, of which the latter kind is shown inFig. 4, on which the blade or bit P is twisted about half a turn inwardto direct it contrary to the direction of the surface of the side of thehoe which it supplements. Said upturned edge serves as a critter, bywhich the mold is severed as it falls on it from the advancing hoe W XIt, a part of the shoved mold being turned inward on the middle of thesown furrow anda part being left on the margin of the same, thusdistributing the mold to effectnally and evenly cover the seed. Theclods 1 and sods encountered by said bits are favorably treated tosecure their reduction, they being cut and torn considerably by themwithout being dragged as clogs on the drill. For the latter reason, too,the curve of the hoe-front W E and the boot-instep F are curved toretreat from the point WV, that trash may be lifted by the mold to bereadily dislodged and cleared from the drill, thus avoiding unclean workby work is difficult and less accessible; third,

they are obstructionless, and do not interfere with the clearing of thehoe of the mold lifted by it, as it simply falls on the bits freely to alower level and different in its operation from rearwardly prolonged andinvolved shearedges.

Returning to the construction of the interior ofthe drill-bootA, it willbe observed that its wall is bulged inward at VV', thus forming acontracted passage at C at the cross-section of the tube, where the seedfalls onto the dividing-ridge T of the distributer, the bulge Vpreventing seeds from falling to the rear undistributed, and the bulge Vand a hump on the forward partof said ridge 1" preventing seed from tooplentifully gliding to the middle of the furrow over the point of thedistributer. The sides of the distributer are. extended slant-shields T,which direct the seed to fall broadcast in the hollow under the expandedhoeWX It. The sides of said distributer are preferably iiared andsomewhat triangular in outline, as shown in Figs. 2 and 6, for thepurposes last sta-ted. Said device is preferably attached by the tenona, thereon to the base of the drill-boot, a stud, d, and nut s holdingit thereto, as shown.

formed at the boot-heel for attaching, as de scribed, a rod, K', issometimes attached to the front part of the 110e or boot-foot, and thedistributer is entered and supported on it in position, as shown in Fig.5.

rIhe anti-clog guard K is also a bent rod, located and directed asshown, attached in manner as last described as a chill or other joint inthe toe-piece J of the drill-boot, and is extended longitudinally overthe hollow of the foot of said boot, and has its rear end, K2, bent anddirected to rest on the parts d s, so, when the drill is thudded onrocks or other hard objects, thus guarding the said guardagainstbreakingorderangement. Said guard may in like manner be insertedinto the nose WV of the hoe. The stud d, or its equivalent, may also beprolonged and bent to serve as the anti-clog guard, but is then lesspractical, as it is more liable to catch at objects passed and bederanged thereby. Its object is to guard the openings against clogging,whereat the seed is delivered broadcast into the furrow.

I do not claim or value an interior bulge or deflection of thedrill-boot wall as a seed-distributer, as that is an insufficient devicefor the purpose when used alone; but I do claim the deiiecting-bulges ofthe same, in combination with my interposed distributer, as guides tocollect the seed centrally thereon to be certainly distributed therefromboth ways in sowing hill-sides.

Having adequately described my invention, what I desire to secure byLetters Patent 0f the United States is- I. The dwarfed hoe R YV X,having the short simple mold-sid es a; and the wide furrowopening treadsR R', prolonged farther rearward than the said mold-sides, incombination directly with drillboot A, made with forwardly-extended footJ, all in one piece, the said parts being constructed and arranged inthe manner as and for the purposes set forth.

2. The anti-clog guard herein set forth, attached to the fore part ofthe drill-boot or the fore part of the hoe, and arranged lon gitudinallyin the hollow of the drill-foot, substantially as and for the purposeset forth.

3. The detachable seed-distributer provided with horizontal tenon a,with sides T, equally flared from the summit T both ways, and heldsustained in position beneath the drill-boot opening by stud d and nuts, in combination with the solid annular protuberance at the out let ofthe drill-boot, to lessen said opening and guide the seed collectedlyonto the middle of said distributer, causing its equal distribution bothways therefrom in sowing inclined as well as level ground, in the manneras and for the purpose set forth.

4. The supplemental blades I? P', made separately from the hoe R W X, incombination therewith by rivets M M', entered through them and the rearends of the shear ends R R', said blades being directed toward eachother IOO IOS

In testimony that I claim the foregoing as 1o my invention I havehereunto set my hand, in presence of two witnesses, this 17th day ofJuly, A. D. 1880.
